Sell by Dates by Karen King

I think publishing can be a bit like this. Someone decides that a book is old-fashioned, out-dated and that people won't be interested in reading it anymore. It's too 'gentle', set too long ago, isn't pacey enough. So the book gets remaindered. Or no more are printed once stocks run out. It doesn't matter that the book is very popular, that people still ask for it. It's past its 'sell by date' so in the bin it goes - metaphorically speaking. No matter how much we ask for a favourite book we can't buy it, unless we are lucky enough to track down a second hand copy on the internet.
To me, the big plus side of e-publishing is that all those wonderful stories that we still want to read but publishers have decided aren't commercial or modern enough are available to us once again. With ebooks there is no 'sell by date'. As long as a reader wants to read them they're available. And as authors, it means that our 'binned' books can be given a new lease of life. Which makes it a winner all around.

yes, don't let old books die. we still read the bible, don't we?
A suggestion would be to look at the 'use by' date as a guide before you buy something.
As for books, I don't truly believe any have what you refer to as a sell by date.
